The conjunction is the part of speech used as a “joiner” for words, phrases, or clauses in a particular sentence. It links these words or groups of words together, in such a way that certain relationships among these different parts of the sentence will be established, and the thoughts that all of these convey will be connected.
An adjective is a part of speech which describes, identifies, or quantifies a noun or a pronoun. So basically, the main function of an adjective is to modify a noun or a pronoun so that it will become more specific and interesting. Instead of just one word, a group of words with a subject and a verb, can also function as an adjective. When this happens, the group of words is called an adjective clause.
A verb can be considered as one of the most important parts of a sentence. You probably already know that a sentence must be composed of a subject and a predicate, so what makes a verb so important? Well, the verb is the main component of a predicate. Without it, there won’t be a sentence, just a bunch of words with an incomplete thought. Simply defined, the verb is a part of speech which is used to demonstrate an action or a state of being.
